Labels are bound to major grid lines on chart area and major ticks on axis area. You can change it’s style via properties axis.style.majorGridLineBrush axis.style.majorTickBrush

But it can be the case when all the lines on your screenshot are major. In that case overlapping labels are culled and you can’t say what label left on screen. You might want to enable minor grid lines and change axis’ properties to keep grid look the same. You can change axis.minorsPerMajor axis.maxAutoTicks Or you can implement your own axis tick provider
